IMPROVEMENT IN SHUTTLES AND SHUTTLE-STOPS FOR LOOMS.

Specification forming part of Letters Patent N 0. 170,214, dated November 23, 1875; application filed May 24, 1875.

To all whom it may concern:

- Be it known that I, JAMES WOLFENDEN, of New Bedford, county of Bristol and State of Massachusetts, have invented an Improved Shuttle and Shuttle-Stop for Looms, of which the following is a specification, reference being had to the accompanying drawings forming part hereof.

My invention consists in a shuttle for looms having its points or ends above the longitudinal central line of the shuttle, as hereinafter particularly described, together with projections or stops set in the throats of the shuttle-boxes, whereby, when the shuttle meets an obstruction during its course through the shed it will be thrown over the obstruction, and through the upper warpthreads of the shed, or will strike against the stops in the throat of the shuttle-box, thereby in either case causing the stopping of the loom.

Figure Us a front elevation of a loom-sley, showing the arrangement of the stops in the throats of the shuttle-boxes. Fig. 2 is a sectional view of the same on the line a: m, Fig.

' 1. Fig. 3 is a side elevation of my improved shuttle. Fig. 4 is a plan of the same. Figs. 5 and 6 are cross-sections of the shed, showing the operation of my shuttle when in contact with an obstruction.

In Fig. 1, A is the race-board. B B are the shuttle boxes, and G is the reed-cap carrying the guard D. In the throats of the shuttle-boxes I set the projections or stops at, as shown, so arranged that the shuttle will clear them when it moves in its proper course upon the race board. When the guard D is not employed a series of stops, d, may be arranged upon the reed-cap dependin g therefrom-swat intervals ofabout half the length of the shuttle which is used. My shuttle S is formed with its points or ends a one-tenth or more of the entire depth of the shuttle above the longitudinal central line thereof, but not carried. up above the line of the upper face of the shuttle. The distance above the longitudinal central line of the shuttle of the points 6 may be varied at pleasure, and still the effect or purpose of having them thus raised will remain the same 5 but I have found it preferable that they should be at least one-tenth of one-half of the whole depth of the shuttle above the longitudinal central line thereof, in order to produce the desired effect, which is to cause the shuttle,

upon meeting an obstruction in the shed, to

beingthrown out over the upper shed or against the stops at in the throats of the shuttle-boxes, will be prevented from entering the box in its course, and thus stop the loom.

Q When the sheds become obstructed, shuttles as ordinarily constructed, with their points located on the line of its longitudinal central line, will very generally pass under the obstruction and produce imperfections, or what are technically termed over-shots in the cloth, while the loom will continue working.

It is evident that by means of my shuttle and shuttle-stops in the throats of the boxes all over-shots are entirely obviated, and. that the loom isstopped when any obstruction or enlargement of the yarn of the shed occurs.

When the points of the shuttle are not carried up to the line of the upper face thereof, the said upper face is preferably cut away at c, as shown, in a straight line from the points 'to about the middle of the shuttle, so that when the shuttle meets an obstruction in the shed the point in the direction in which it is moving will be thrown up as the highest part of the shuttle, and will not be obstructed in its passage through the upper shed.-

What I claim as my invention, and desire to ,secure by Letters Patent, is

1. The shuttle S, having its points or ends 6 above the longitudinal central line thereof, as described, and for the purpose specified.

2. The combination, with the sley of a loom, of the stops a, arranged at the throat of the shuttle-boxes, as and for the purpose set forth.

JAMES WOLFENDEN.
